Detailed Description

Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the disclosure. One skilled in the relevant art will recognize, however, that the subject matter of the present disclosure can be practiced without one or more of the specific details, or with other methods, components, devices, steps, and the like. In other instances, well-known technical solutions have not been shown or described in detail to avoid obscuring aspects of the present disclosure.

Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus their repetitive description will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor devices and/or microcontroller devices.

In the initial stage of building an LTE (Long Term Evolution) network, a telecommunications carrier generally selects to build a site with a relatively high position, for example, about 20-30 th of a building, because the number of sites of a base station is small. Such a higher positioned station may be referred to simply as a high station. With the continuous construction of networks, in order to strengthen deep coverage and solve the high load problem, a new base station is added near a high station, and overlapping coverage is formed between the new base station and an old high station. The situation is common in the scenes of business circles, schools and the like, for example, in school student dormitories, outdoor stations can cover the student dormitories, and indoor stations can be built in the students dormitory buildings; on the other hand, they cause interference to surrounding newly-built base stations.

Because the acquisition difficulty of the initial station address is high, the high station cannot be simply dismantled under the general condition, and a new station may not be covered in a partial area covered by the high station. It becomes a problem whether the high station can be removed or not. According to the traditional method, a network optimization person can firstly carry out a large amount of manual tests, the overlapping coverage condition of the high station and other stations is calculated according to the test condition, and if the new station completely covers the coverage range of the high station, the high station can be considered to be dismantled. If the new station fails to fully cover the coverage of the high station, the high station cannot be dismantled. Network optimization personnel generally select to adjust the downward inclination angle of the antenna of the high station to control the coverage area of the high station, or set a timing task on a network manager to adjust the RS (Reference Signal) power of the high station at regular time when the base station is busy to control the coverage area of the high station.

This conventional approach to handling high stations has three problems: on one hand, CQT (Call Quality Test) is complex, consumes manpower and has low efficiency; on the other hand, when the RS power is adjusted for a high station, the adjustment amplitude cannot be accurately evaluated, and the RS power can be reduced to a certain value generally only according to manual experience; on the other hand, the flexibility of the network management to set the timing task is not enough, and the timing task cannot be dynamically adjusted according to the busy and idle conditions of the high station.

Based on this, in the present exemplary embodiment, first, a method for calculating an overlapping coverage of a base station is provided, where the method may be executed in a terminal device, a server cluster, a cloud server, or the like; of course, those skilled in the art may also operate the method of the present disclosure on other platforms as needed, which is not particularly limited in the exemplary embodiment. Referring to fig. 1, the method for calculating the overlapping coverage of the base station may include the steps of:

s110, acquiring first measurement report data and second measurement report data; the first measurement report data is obtained by measuring signal quality data of a neighboring cell which is not covered by the current base station by user equipment which has a connection relation with the current base station, and the second measurement report data is obtained by measuring signal quality data of a current service cell which is covered by the current base station by the user equipment;

step S120, determining a current grid area to which the first measurement report data and the second measurement report data belong according to longitude and latitude information of the user equipment, and calculating the signal intensity of an adjacent cell of the current grid area according to the first measurement report data;

s130, determining whether the current grid region belongs to an overlapping coverage grid or not according to the signal intensity of the neighbor cell, and calculating the overlapping coverage rate of the current base station when the current grid region is determined to belong to the overlapping coverage grid;

step S140, determining whether the current base station is a detachable base station according to the overlapping coverage rate of the current base station, and adjusting the current power of the current base station when the current base station is determined to be a non-detachable base station.

In the method for calculating the overlapping coverage of the base station, on one hand, the current grid area to which the first measurement report data and the second measurement report data belong can be determined according to the longitude and latitude information of the user equipment, and the signal intensity of the adjacent cell of the current grid area is calculated according to the first measurement report data; determining whether the current grid region belongs to an overlapping coverage grid or not according to the signal intensity of the adjacent cell, and calculating the overlapping coverage rate of the current base station when the current grid region is determined to belong to the overlapping coverage grid; finally, when the current base station is determined to be a non-detachable base station, the current power of the current base station is adjusted, so that the current power of the current base station is automatically adjusted, the current power of the base station is not required to be adjusted up or down through the manual experience of network optimization personnel, and the power adjustment efficiency is improved; on the other hand, whether the current base station is a detachable base station is determined according to the overlapping coverage rate of the current base station, and when the current base station is determined to be not the detachable base station, the current power of the current base station is adjusted, so that the judgment on whether the current base station is the detachable base station is realized; meanwhile, when the current base station is determined to be a detachable base station, the current base station can be detached in time, and therefore resources wasted by the base station are saved.

Hereinafter, the method for calculating the overlapping coverage of the base station according to the exemplary embodiment of the present disclosure will be explained and explained in detail with reference to the drawings.

First, the objects of the exemplary embodiments of the present disclosure are explained and illustrated. Specifically, the embodiment of the disclosure calculates the overlapping coverage condition of the high station and other surrounding base stations by using wireless big data, and provides scientific basis for dismantling the high station. Meanwhile, for the high stations which cannot be detached, the maximum RS power adjustment amplitude of the high stations is calculated through wireless big data, then the RRC (Radio Resource Control) connection number and the PRB (Physical Resource Block) utilization rate of the high stations are monitored on a big data platform in real time, when the high stations are busy, the RS power of the high stations is dynamically adjusted through a northbound MML (Man-Machine Language) interface, the coverage range of the high stations is controlled, the high stations can be effectively utilized, and the interference of the high stations on other base stations is reduced.

Next, an overlapping coverage calculation system of a base station of the exemplary embodiment of the present disclosure is explained and explained. Specifically, referring to fig. 2, the system for calculating the overlapping coverage of the base station may include a current base station 210, a user equipment 220, and a server platform 230. Wherein, the current base station 210, the user equipment 220 and the server platform 230 are sequentially connected with a network.

Specifically, the current base station is configured to provide a network signal for the user equipment and the server platform, and simultaneously, periodically send an MR data acquisition request to the user equipment having a connection relationship with the current base station; the user equipment is used for acquiring MR data and feeding the MR data back to the current base station, and the server platform is used for realizing the method for calculating the overlapping coverage rate of the base station in the embodiment of the disclosure.

Further, in a method for calculating an overlapping coverage rate of a base station provided in an exemplary embodiment of the present disclosure:

in step S110, first measurement report data and second measurement report data are acquired; the first measurement report data is obtained by measuring, by the user equipment having a connection relationship with the current base station, signal quality data of a neighboring cell not covered by the current base station, and the second measurement report data is obtained by measuring, by the user equipment, signal quality data of a current serving cell covered by the current base station.

Specifically, the current base station may periodically send an MR data acquisition request to each User Equipment (UE) that maintains a connection relationship with the current base station, and after receiving the MR data acquisition request, the User Equipment may measure signal quality data of a neighboring cell that is not covered by the current base station, thereby obtaining first measurement report data, measure signal quality data of a current serving cell that is covered by the current base station, obtain second measurement report data, and report the first measurement report data and the second measurement report data to the current base station; when the overlapping coverage rate of the current base station needs to be calculated, the first measurement report data and the second measurement report data can be obtained. The UE may report the signal conditions of the current serving cell and the neighboring cell served by the current base station to the base station through the MR data; MR data can include three formats: MRO, MRE, and MRS; the content screenshot of the 4G MRO data may specifically refer to fig. 3.

Specifically, in fig. 3, the number of the 4G base station currently occupied by the UE may include an enodeb id and cell number information CELLID, and each UE may report, to the current base station, information such as the signal strength of the current serving cell covered by the current base station, the signal strength of the neighboring cell not covered by the current base station, the frequency point number of the current serving cell, and the frequency point number of the neighboring cell; meanwhile, when the UE reports the first measurement report data and the second measurement report data, the UE also reports the longitude and latitude information of the UE, so that rasterization processing is carried out on the first measurement report data and the second measurement report data according to the longitude and latitude information of the UE. It should be added that, in the process of reporting data, the UE packages the first measurement report data, the second measurement report data, and the latitude and longitude information, and then generates an AGPS data packet for uploading, where the AGPS data packet is an Assisted Global Positioning System (Assisted Global Positioning System) data packet.

In step S120, according to the latitude and longitude information of the ue, a current grid area to which the first measurement report data and the second measurement report data belong is determined, and the neighboring cell signal strength of the current grid area is calculated according to the first measurement report data.

In this exemplary embodiment, first, a current grid area to which the first measurement report data belongs is determined according to latitude and longitude information of the user equipment. Specifically, as shown in fig. 4, the method may include the following steps:

step S410, when it is determined that the first measurement report data includes a plurality of co-frequency cells and inter-frequency cells of the same site, deleting the signal quality data of the co-frequency cells and the inter-frequency cells of the same site in the first measurement report data to obtain target measurement report data.

Step S420, when it is determined that the target measurement report data includes a plurality of neighboring cell signal strengths, taking the neighboring cell signal with the strongest signal strength in the second measurement report data as the target signal strength.

Step S430, determining the current grid area of the adjacent cell in the world map according to the latitude and longitude information of the user equipment, and putting the target signal intensity into the current grid area.

Hereinafter, steps S410 to S430 will be explained and explained. Specifically, if there are multiple pieces of neighboring cell information in the longitude and latitude and neighboring cell signal strength reported by one UE, only the strongest neighboring cell signal strength is counted, and AGPS data of the co-frequency cell and the inter-frequency cell of the same site need to be deleted when counting data (because these cells of the same site may also be removed or RS power is reduced); and then, determining the current grid area of the adjacent cell in the world map according to the latitude and longitude information of the UE, and counting the target signal intensity into the specific current grid area. The target signal strength counted in each current grid region may be specifically as shown in fig. 5.

Secondly, the signal intensity of the adjacent cell of the current grid area is calculated according to the first measurement report data. Specifically, the method may include: firstly, carrying out summation operation on the target signal intensity in the current grid region, and calculating the average value of the summation operation result; and secondly, taking the average value as the signal intensity of the adjacent cell of the current grid area. Specifically, since the longitude and latitude information of the UEs reported by the multiple UEs may be in the same current grid area, an average value of strongest neighbor signals (target signal strengths) reported by the UEs in each current grid area may be calculated as the neighbor signal strength of the current grid area. The neighboring cell signal strength of each current grid region may be as shown in table 1 below:

TABLE 1

Base station numbering	Cell numbering	Grid numbering	Serving cell RSRP average	Average value of RSRP of adjacent cell signals
					410751	11	Grid 1	-83	-92
410751	11	Grid 2	-95	-100
					410751	11	Grid 3	-94	-95
410751	11	Grid 4	-70	-81
					410751	11	Grid 5	-85	-98
410751	11	Grid 6	-72	-92
					410751	11	Grid 7	-89	-90
410751	11	Grid 8	-96	-101
					410751	11	Grid 9	-100	-105

In table 1, the average value of the Reference Signal Receiving Power (Reference Signal Receiving Power) of the serving cell RSRP represents the Signal strength of the current serving cell, and the average value of the neighboring cell Signal RSRP represents the Signal strength of the neighboring cell; the neighbor cell signal strength of each neighbor cell may refer to fig. 6.

In step S130, it is determined whether the current grid region belongs to an overlapping coverage grid according to the neighboring cell signal strength, and when it is determined that the current grid region belongs to the overlapping coverage grid, an overlapping coverage rate of the current base station is calculated.

In this exemplary embodiment, first, it is determined whether the current grid region belongs to an overlapping coverage grid according to the neighbor cell signal strength. Specifically, the method may include: firstly, judging whether the signal intensity of the adjacent cell is greater than a preset low service level threshold value; secondly, determining whether the current grid region belongs to an overlapping coverage grid or not according to a judgment result; wherein, if the judgment result is: if the signal intensity of the neighbor cell is greater than a preset low service level threshold value, the current grid region belongs to an overlapped coverage grid; if the judgment result is that: and if the signal intensity of the adjacent cell is lower than a preset low service level threshold value, the current grid region belongs to a non-overlapping coverage grid.

Specifically, first, a minimum service level (e.g., -100dBm) for a signal service may be set; secondly, when the signal intensity of the adjacent cell is higher than the lowest service level, which indicates that the main service cell reduces RS power, the adjacent cell signal can take over the high station to continue providing service, and the grid belongs to an overlapped covering grid; otherwise, if the signal strength of the neighboring cell in a certain grid does not reach the threshold, it indicates that after the high station signal is weakened, the signal of the neighboring cell may not provide service for the mobile phone, and the grid belongs to a non-overlapping coverage grid.

Further, when it is determined that the current grid area belongs to the overlapping coverage grid, the overlapping coverage rate of the current base station is calculated. The calculating the overlapping coverage rate of the current base station may include: firstly, calculating a first grid number of a current grid area covered by the current base station and a second grid number of overlapped coverage grids covered by the current base station; and secondly, calculating the proportion of the second grid quantity in the first grid quantity to obtain the overlapping coverage rate of the current base station. That is, the overlapping coverage of all grids covered by all the high stations (current base stations) can be summarized and counted, and the number of overlapping coverage grids/all the coverage grids of the high stations can be used to obtain the overlapping coverage of the high stations (current base stations).

In step S140, it is determined whether the current base station is a detachable base station according to the overlapping coverage of the current base station, and when the current base station is determined to be a non-detachable base station, the current power of the current base station is adjusted.

In the present exemplary embodiment, first, it is determined whether the current base station is a detachable base station according to the overlapping coverage of the current base station. Specifically, the method may include: judging whether the overlapping coverage rate of the current base station is greater than a preset coverage rate threshold value; if the overlapping coverage rate of the current base station is greater than a preset coverage rate threshold value, determining that the current base station is a detachable base station; and if the overlapping coverage rate of the current base station is less than or equal to a preset coverage rate threshold value, determining that the current base station is a non-detachable base station. For example, if the overlapping coverage of a high station (current base station) is relatively high, for example, it reaches 95% (preset coverage threshold) or more, it indicates that there is a new station around the high station for effective coverage, and under the condition that the load meets the requirement, the high station may be considered to be removed; meanwhile, for a high station with low overlapping coverage rate, the high station cannot be dismantled, but the RS power can be dynamically adjusted.

Further, referring to fig. 7, adjusting the current power of the current base station may include the following steps:

step S710, acquiring a target grid area belonging to a non-overlapping coverage grid in a current grid area, and acquiring second measurement report data in the target grid area;

step S720, calculating a power average value of the reference signal received power in the second measurement report data, and calculating a power adjustment threshold value according to the power average value and a preset low service level threshold value;

and step S730, adjusting the current power of the current base station according to the power adjustment threshold.

Adjusting the current power of the current base station according to the power adjustment threshold may include: firstly, calculating the RRC connection number and the PRB utilization rate of the current base station; secondly, if the RRC connection number is larger than a preset connection number and/or the PRB utilization rate is larger than a preset utilization rate, adjusting the current power downwards according to the power adjustment threshold; further, if the RRC connection number is smaller than a preset connection number and the PRB utilization rate is smaller than a preset utilization rate, the current power is adjusted up according to the power adjustment threshold.

Hereinafter, steps S710 to S730 will be explained and explained. Specifically, in all non-overlapping coverage grids (non-overlapping coverage grids), the difference between the minimum value of the average values of the RSRP of the serving cells and the lowest service level is taken as the maximum amplitude of the RS power adjustment. For example, a grid 96dBm indicated by an arrow in fig. 6 is the minimum of the average values of the RSRP of the serving cells in the non-overlapping coverage grid, 100-96 being 4 dB. This means that if the RS power of a high station is adjusted down by 4dB, the coverage area of the high station can still provide reliable service for the handset. And after the RS power of the high station is adjusted to be low, the interference to other base station cells can be reduced.

Furthermore, high stations in the scenes of business circles, schools and the like have a tide effect, and the RS power of the high stations can be dynamically adjusted according to the busy and idle conditions of the high stations. When the number of users of an RRC (Radio Resource Control) of a base station is large and the utilization rate of a Physical Resource Block (PRB) is high, the RS power can be adjusted downwards according to the maximum amplitude of the RS power adjustment obtained by the previous calculation; when the number of RRC users is small and the PRB utilization rate is low, the RS power can be restored to a normal value (or the power adjustment threshold value is adjusted upwards).

Further, the dynamic adjustment of the current power of the current base station can be realized as follows. Firstly, based on a preset north-oriented MML (Man-Machine Language) command interface development guideline, operations such as querying, resetting, parameter modification and the like are performed on a current base station. Secondly, the big data platform adopts SOCKET programming, and executes a control command generated by the big data platform through a northbound MML interface provided by a professional network manager, so that the RS power of the base station is dynamically adjusted. Meanwhile, when the RS power of the Base station is adjusted by a professional network manager, a specific BBU (Building Base-band Unit, indoor baseband processing Unit) name and a cell number need to be specified; however, the name of BBU on the network manager of the current network sometimes changes, for example, adds information such as "debug" or "restore" and the like; in order to solve the technical problem, the big data platform can acquire the latest name of each BBU through a north direction I1 interface, and can also acquire the corresponding relation between the base station number of the BBU and the name of the BBU in real time through issuing an LST ENODEBFUNCTION command through a north direction MML interface.

In the implementation process of a specific scheme, the most convenient method for the big data platform to obtain more RRC users and high PRB utilization rate is to extract the RRC users from the performance data of the wireless base station; therefore, according to the technical requirements of the 4G wireless integrated network management interface, the indexes of a large number of RRC users and the PRB utilization rate can be extracted from the performance data of the northbound I1 interface. The performance index file is generally 15-minute granularity, and the big data platform acquires the performance index file in real time, so that the user number condition of RRC connection and the PDSCH peak PRB utilization ratio condition of the cell in the 15-minute granularity can be known.

Further, the manner of the single command to modify the RS power of the current base station may include: the I4 interfaces of the professional network management all adopt a northbound MML command mode, and the login of the network management in a TELNET mode can be realized through SOCKET programming, wherein the single base station command issuing step is as follows:

inputting a RemoteHost and a RemotePort, and connecting a wireless network management I4 interface;

inputting a command LGI, wherein OP is a user name, PWD is a password, and login authentication is carried out;

with REGNE, name ═ BBU name; and logging in the base station.

After logging in a single base station, an RS parameter modification operation instruction can be issued: MOD PDSCHCFG LOCALCELLID is 0, and REFERENCESIGNALPWR is xxx.

The method for adjusting the RS power of each base station cell in batch may include: first, a script file for modifying RS power is generated, and a line of commands is generated for each cell. As follows:

MOD PDSCHCFG, LOCALCELLID is 0, REFERENCESIGNALPWR is xxx; { BBU name }. The large data platform can dynamically set the RS value of each cell according to the busy and idle conditions of each cell of the base station in front, and generate an MML script file; the script file is in a TXT format, and a specific BBU name needs to be carried behind each line of commands;

secondly, the big data platform uploads the MML script file to a wireless network management batch processing directory by using FTP through a wireless network management I1 interface:

/export/home/sysm/ftproot/itf_n/nms_mml_server/script

then, the big data platform is connected to the wireless network management through an I4 interface, the method refers to the first two steps of the single base station command issuing, and then executes a command S _ ACTIVATE, wherein, FILE is the MML script FILE txt;

furthermore, the wireless network manager executes each command in the MML script file txt in a concurrent mode, and stores the detailed executed result in an MML result directory:

/export/home/sysm/ftproot/itf_n/nms_mml_server/result。

the file format of the execution result storage is a file in an rst format.

And finally, the big data platform can retrieve the star rst file in the MML execution result directory by FTP through the I1 interface again through the wireless network management.

Hereinafter, the method for calculating the overlapping coverage of the base station according to the exemplary embodiment of the present disclosure is further explained and explained with reference to fig. 8. Specifically, referring to fig. 8, the method for calculating the overlapping coverage of the base station may include the following steps:

step S801, acquiring AGPS data reported by user equipment, and determining a current grid area to which first measurement report data and second measurement report data belong, wherein the first measurement report data and the second measurement report data belong, according to longitude and latitude information included in the AGPS data;

step S802, calculating the signal intensity of the adjacent cell of the current grid area, and judging whether the current grid area belongs to the overlapped coverage grid or not according to the signal intensity of the adjacent cell; if yes, jumping to step S803; if not, jumping to step S806;

step S803, according to the proportion of the overlapping coverage grid in all the current grid areas, judging whether the current base station belongs to a detachable base station; if yes, jumping to step S805; if not, jumping to step S804;

step S804, dynamically adjusting the RS power of the current base station;

step S805, generating detachable information corresponding to the current base station, and sending the detachable information to a corresponding manager;

in step S806, the current grid region is determined as a non-overlapping overlay grid.

On one hand, compared with the traditional manual field test, the method for calculating the overlapping coverage rate of the base station provided by the embodiment of the disclosure adopts wireless big data to calculate the overlapping coverage rate of the high station and judge whether the high station can be detached, and is more scientific and reasonable in method and higher in efficiency; on the other hand, compared with the traditional method of setting a timing task on a network manager to adjust the RS power of a high station at a fixed time, the method not only provides the maximum amplitude of the RS power adjustment, but also can use a northbound MML interface to realize the dynamic adjustment of the RS power according to performance data; on the other hand, if the name of the BBU in the current network is changed, when the RS power is adjusted by setting a timing task in the conventional network manager, the name of the BBU in the timing task script needs to be modified again, otherwise the execution script will report an error. When the large data platform executes the dynamic RS power adjustment, the large data can automatically update the BBU name in the script in the step of generating the MML script, so that the MML script can be correctly executed.

The embodiment of the disclosure also provides a device for calculating the overlapping coverage rate of the base station.
